A convenient transformation of α-alkylserines into α-halogenomethyl-α-alkylglycines
摘要:
An efficient and facile synthesis of N-Boc-alpha-chloromethyl- and alpha-bromomethyl-alpha-alkylglycines is reported that involves cyclization of N-Boc-alpha-alkylserines to the corresponding beta-lactones under Mitsunobu reaction conditions, followed by ring opening with anhydrous MgCl2 or MgBr2.
